Definitions

  • the present invention relates to a structural element for obtaining three-dimensional constructions.
  • the object of the invention is to make available a structural element having a particularly simple and economical configuration from the constructional point of view, and at the same time capable of being effectively used for the composition of grid structures, also complex ones, both in the field of three-dimensional construction games, and in the civil and industrial field.
  • An additional object of the invention is to provide a structural element able to be coupled in simple and rapid fashion with similar structural elements to form three-dimensional grid structures with high intrinsic strength.
  • a structural element that is essentially characterised in that it consists of a body in the form of a generally planar tripod, with three equidistant arms whose free ends are arranged to be angularly deviated from a same side relative to the general plane of the tripod body to achieve their union with the free ends of the arms of similar tripod bodies in order to form an approximately spherical grid structure.
  • said grid structure is generated by the union of eight of the aforesaid structural elements.
  • Figures 1, 2 and 3, 4 show the structural element according to the invention respectively of a first and of a second type: as will be shown hereafter, they have such a conformation as to be able to be mutually connected to generate grid structure that is - so to speak - elementary, in turn connectable with identical grid structures to form complex three-dimensional constructions.
  • Each structural element 1,2 consists of a body in the form of a generally planar tripod, having three angularly equidistant arms 1a, 2a which extend from a central part 1b, 2b.
  • This central part is preferably, but - as will be shown - not necessarily hollow, and the arms 1a, 2a can be at least partially hollow.
  • Each arm 1a, 2a has a respective free end 1c, 2c, opposite to the central part 1b, 2b, which is arranged to be deviated angularly relative to the general plane of the tripod body.
  • the structural elements 1, 2 can be produced with different materials, for example elastomers or thermosetting materials and even metallic materials, such as light alloys, or high strength composite materials, particularly if the structural elements 1 and 2 are destined to build industrial or civil structures (beams, trestles, cranes, floating structures, impact-resistant panels, protective shells, signposts, ladders and mezzanine floors, load-bearing structures for industrial and sporting buildings, roofs for greenhouses and roofs in general, roof elements and composite beams, etc.).
  • industrial or civil structures beams, trestles, cranes, floating structures, impact-resistant panels, protective shells, signposts, ladders and mezzanine floors, load-bearing structures for industrial and sporting buildings, roofs for greenhouses and roofs in general, roof elements and composite beams, etc.
  • the angular deviation of the free ends 1c, 2c of the three arms 1a, 2a of each structural element 1, 2 will be in the same direction, i.e. at the same side relative to the general plane of the tripod body.
  • the free ends 1c, 2c of the arms 1a, 2a of the structural elements 1, 2 are preferably, but not necessarily, provided with formations for rapid mutual coupling. This arrangement is the chosen one if the structural elements are to constitute components for three-dimensional construction games, whereas as shall be seen it is not normally provided if the structural elements are intended for the construction of civil and industrial structures.
  • the structural element 1 is the conformation of said formations for rapid mutual coupling: in the case of the structural element 1, the formations consist of pairs of contiguous hook-like projections 3, facing the same way relative to the general plane of the tripod structural element 1. In the case of the structural element 2 the free ends 2c are formed with a through opening 4 able to be engaged, by means of a set-in or snap-in coupling, by the hook-like projections 3. In this way, each arm 1a of the structural element 1 can be coupled with an arm 2a of a respective structural element 2, and vice versa.
  • junction element 9 which can also be made of a single piece of moulded plastic material or similar material, consists of two parts 10, 11 mutually articulated in book fashion around a flexible hinge 12 and whereof the first one has a pair of projections with engaging teeth 13 able to be engaged in set-in or snap-in fashion into corresponding hollow recesses 14 of the second part, as a result of their mutual superposition in the manner shown in Figure 9.
  • each structural element 1, 2 may consist simply of a tripod body of the type illustrated by the reference number 15 in Figure 7, the free ends 15c of whose arms 15a projecting from the central element 15b may be joined to the free ends of similar elements 15 with traditional mechanical systems such as welding, bolting and the like.
  • the free ends 15c may be angularly deviated in such a way that the mutual union between the arms 15a of eight structural elements 15 will generate an approximately spherical grid structure similar to the structure 5 of Figure 5, and said grid structures may then be mutually connected (in this case also by means of conventional mechanical junction systems) to obtain complex three-dimensional grid constructions with high intrinsic strength.
  • FIG. 10 and 11, 12 and 13, 14 and 15, 16 and 17. Further alternative embodiments of the tripod which can be employed in the grid structure according to the invention are depicted in Figures 10 and 11, 12 and 13, 14 and 15, 16 and 17. These embodiments differ from what has been previously disclosed, and from one another, only in connection with a different constructive arrangement, also as far as the formations for mutual rapid coupling are concerned, in addition to the fact of being provided with a generally non planar but slightly curved or convex configuration, with their central part having a substantially spherical surface. Morever in these alternative embodiments the three arms are connected to the central part having a substantially spherical surface through elastically deformable intermediate sections. This enables an easier composition of the elementary grid structures formed by the mutual connection of the tripods.
  • Figures 18 and 19, 20 and 21, 22 and 23 show different constructive arrangements of spacer members (respectively a two-way straight configuration, a two-way angled configuration and a four-way cross configuration) which can be employed to build up complex grid structures deriving by the union of two or more elementary grid structures.
